Hot water feels so good in a shower, very relaxing. So it's very shocking when the water suddenly becomes freezing cold. Argh. Shut off water. Open up the flow again. But no water comes out! Unless the tap is turned to the cold position. So bear the freezing cold water. After all, it wakes you up. But I was already awake.

"Bobby, we're changing the hot water tank!"
"Do you want us to turn the hot water back on?"
"No, it's ok, I'm done."
Cold showers are good for you. Really. They build character.
